The contact owned a 2003 Lincoln Navigator. The contact stated that fifteen minutes after she parked and turned off the vehicle in the driveway, her brother alerted her that the driver's side front seat had caught fire. The air bags were deployed. The fire department arrived on the scene and extinguished the fire. The fire department determined that the cause of the fire was an electrical system failure. A fire department report was filed. The vehicle remained in the driveway and was not yet deemed totaled by the insurance company. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA Hotline. Prior to the failure, the gear shifter and driver's side front seat made grinding noises, and the passenger's side front window made clicking noises while driving. The failure mileage was 120,196.

This article supersedes TSB 22-2219 to update the Parts List and Service Procedure to clarify applicable steps by vehicle application. Some 2003-2020 Expedition/Navigator and 2006-2020 F-150 (non-Raptor) vehicles equipped with 4WD may exhibit grinding/clicking/ratcheting noise from the front wheel area. This may be due to partial engagement of the integrated wheel ends (IWE). To correct this condition, follow the Service Procedure to remove and cap the vacuum supply line or to reprogram the transfer case control module (TCCM) and replace any worn vacuum and/or IWE components.

For 2000-2024 Ford and Lincoln vehicles, swapping a module from a vehicle for diagnosis purposes is likely to cause errors and is not recommended. It is also not recommended to order a replacement module using a vehicle identification number (VIN) from a different vehicle. Most modules on these affected vehicles are VIN/vehicle specific and hardware variations between modules do exist. Swapping a module from a vehicle or ordering a module using a different vehicle/VIN can cause ineffective repairs and additional vehicle down time. Make sure all appropriate Workshop Manual (WSM) procedures are followed when diagnosing the condition prior to all module replacements and only order modules using the correct VIN.

This may be due to partial engagement of the integrated wheel ends (IWE). To correct this condition, follow the Service Procedure steps to remove and cap the vacuum supply line.
